# This file only contains a selection of the most common options. For a full
# list see the documentation:
# https://www.sphinx-doc.org/en/master/usage/configuration.html

# -- Path setup --------------------------------------------------------------

# If extensions (or modules to document with autodoc) are in another directory,
# add these directories to sys.path here. If the directory is relative to the
# documentation root, use os.path.abspath to make it absolute, like shown here.

        return sub.stdout

# -- Project information -----------------------------------------------------

project = 'oneDNN'
copyright = '2016-2022 Intel Corporation'
author = ''

# -- General configuration ---------------------------------------------------

# Add any Sphinx extension module names here, as strings. They can be
# extensions coming with Sphinx (named 'sphinx.ext.*') or your custom
# ones.

# Specify the path to Doxyrest extensions for Sphinx:

# Add Doxyrest extensions ``doxyrest`` and ``cpplexer``:

extensions = ['doxyrest', 'cpplexer']

# If you used INTRO_FILE in 'doxyrest-config.lua' to force-include it
# into 'index.rst', exclude it from the Sphinx input (otherwise, there
# will be build warnings):
